Switching The Outputs At Comparison Values; Position Input For Motion Control - Siemens SIMATIC ET 200SP Manual

2.2.3

Switching the outputs at comparison values

You define two comparison values that can control the two digital outputs independent of the
user program. The comparison values are configurable and can be modified during runtime
with the user program.
Comparison values in the Counting mode
Depending on the encoder, you define two position or counter values as comparison values
in the Counting mode. If the current position or counter value meets the configured
comparison condition, the corresponding digital output can be set to directly initiate control
processes in the process.
Comparison values in the Measuring mode
You define two comparison values in the Measuring mode. If the current measured value
meets the configured comparison condition, the corresponding digital output can be set to
directly initiate control processes in the process.

Position input for Motion Control

You can use the technology module for position input with S7-1500 Motion Control .
In the device configuration of the technology module in STEP 7 (TIA Portal), select "Position
input for Motion Control" mode.
When using an incremental encoder or pulse encoder, the position input is based on the
counting function of the technology module. With an SSI absolute encoder, the absolute
value is read in via a synchronous, serial interface and prepared according to the parameter
assignment to be made available for S7-1500 Motion Control.
Additional information
A detailed description of the use of Motion Control and its configuration is available in the
function manual S7-1500 Motion Control as a download from the Internet
